Definitions

• the invention relates to a method for dispensing pressure-sensitive adhesive laminates or laminate sections from a movable primary to a movable secondary carrier web, the laminates being detached when the primary web is deflected around a dispenser edge and dispensed onto the secondary web.
• laminate adhesive laminate sections are known. These can e.g. are labels, stickers, transdermal therapy systems (TTS) or double-sided adhesive tape.
• TTS transdermal therapy systems
• the pressure-sensitive adhesive surface or a pressure-sensitive adhesive matrix of these laminate sections is usually covered by a carrier web that at least partially projects over them.
• these laminate sections are produced by stamping a matrix and a backing layer connected to it with the aid of a suitable tool up to the carrier web and pulling off and discarding a protruding grid of matrix and a backing layer.
• the method presupposes that a transdermal therapeutic system to be transferred can be detached from a primary carrier web when guided over a dispenser edge, and can thus be transferred to the final, secondary carrier web.
• this method can no longer be used because the pressure-sensitive adhesive matrix then no longer detaches from the primary carrier web, but is deflected with the primary carrier web.
• the primary carrier web is isolated with isolated laminate sections, e.g. Bandage, guided in the direction of transport over a dispenser edge, whereby the
• Plaster is peeled off the carrier web over its entire width.
• the peeling process runs in the direction of the web. If the plaster adheres very strongly to the primary carrier layer, the plaster can be pulled around the edge without detaching from the primary carrier web, even at a very acute dispensing angle, so that a dispensing process is not possible.
• the invention has for its object to provide a method and an apparatus of the type specified in the preamble of claim 1, which overcome the difficulties and technical limits mentioned and are suitable without problems, even strongly pressure-sensitive adhesive laminate sections from their carrier web when deflecting to release a dispenser edge and dispense it on a movable secondary carrier web.

• the dispenser edge is designed in such a way that the at least two strips of the first carrier web are deflected at separate sections of the dispenser edge.
• the dispenser edge thus has two sections, on each of which a strip is deflected, preferably in a different direction.
• the two sections of the dispenser edge are arranged in a non-linear manner.
• There is an angle between the two sections of the dispenser edge which is between 1 ° to 179 ° or 181 ° to 359 °.
• the dividing line or the predetermined breaking line between the two strips of the first carrier web runs exactly above the intersection of the two sections of the dispenser edge.
• the subdivision of the primary web into at least two strips, which are pulled off individually from the dispenser edge, results in a stabilization of the plaster in the web direction during the dispensing process. This is favored in the case of a non-linear configuration of the dispenser edge in that the strips are not pulled off to one or both sides in the tape running direction but at an angle to the tape running direction.
• An alternative embodiment of the method in which the primary web is separated into at least three strips (ie equipped with at least two separating or predetermined breaking lines), is characterized in that the first or the inner strips of the primary web are at a first section the dispenser edge is deflected and is removed from the primary web and the laminates still adhering to it.
• the pressure-sensitive adhesive laminates remain connected to the outer strips of the primary web.
• the outer strips are then deflected over further sections of the dispenser edge, the pressure-sensitive adhesive laminates being finally removed and dispensed onto the secondary web.
• each strip of the primary carrier web covers only a partial area of the pressure-sensitive adhesive surface of the laminate section, which consequently has to overcome only a fraction of the total adhesive force for detachment, the detachment of a strongly pressure-sensitive adhesive laminate section can be carried out strip by strip simultaneously or successively in several stages without difficulty become.
• the method according to the invention can also make use of the measure that the primary carrier web is guided at a lower transport speed relative to the secondary carrier web.
• This enables, for example, late placement or adhesion of a pressure-sensitive adhesive laminate section to the secondary carrier web, only a small part remaining adhering to the primary web.
• extensive differences in the web speeds between the primary and secondary web can be realized, whereby the distances between the individual systems can be increased without further measures.
